Abstract (en)
[origin: EP1886986A1] An iodine-containing fluoropolyether represented by the following general formula [I]: €ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒRfO[CF(CF 3 )CF 2 O]mCF(CF 3 )(CH 2 )nI€ƒ€ƒ€ƒ€ƒ€ƒ[I] (where Rf is a perfluoroalkyl group having 1-3 carbon atoms, m is an integer of 0-10, and n is an integer of 3-12), is a novel compound having a perfluoropolyetheralkyl group capable of giving a flexibility to the molecule chain through the etheral bond, said perfluoropolyether alkyl group being bonded to the alkyl iodide having an alkyl group having 3 or more carbon atoms, and can be produced by reaction of a fluoropolyether group-containing alcohol represented by the following general formula [II]: €ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒRfO[CF(CF 3 )CF 2 O]mCF(CF 3 )(CH 2 )nOH€ƒ€ƒ€ƒ€ƒ€ƒ[II] (Where Rf, m, avd n have the same meanings as defined above) with a metal iodide, preferably potassium iodide.
